` fr n EDWARD C. DUCKETT AND FRANK B. LLGYD, 0F SPOKANE, WASHINGTON.

GOPHER-EXTERMINATOR.

To all whom it may concern:

Be it known that we, EDWARD C. DUCKETT and FRANK B. LLOYD, citizens ofthe United States, residing at Spokane, in the county of Spokane andState of lVashington, have invented certain new and useful Improvementsin Gopher-Exterminators, of which the follo-wing is a specilication.

This invention relates to gopher exterminators of that kindcharacterized by a tube which is filled with hay or some othercombustible material, together with a fumigating substance such assulfur, the same being ignited, and the resulting smoke and fumes forcedinto the gopher hole.

It is the object of the present invention toprovide a device of the kindstated which is simple in structure, and reliable and efficacious, andalso one which may be easily handled, and without discomfort to theoperator.

Vith the foregoing objects in view, the invention consists in a novelconstruction and arrangement of parts to be hereinafter described andclaimed, reference being had to the drawing` hereto annexed forming apart of this specification, in which drawing- Figure 1 is an elevationof the device. Fig. 2 is a longitudinal section thereof. Fig. 3 is anenlarged sectional detail of the check valve, and Fig. l is a plan viewof the grate hereinafter referred to.

In the drawing, 5 denotes a tube which is tapered at one of its endsindicated at (i, said end being' the one which is insert-ed into themouth of the gopher hole. To the other end of the tube is connected apump for forcing the fumes into the gopher hole, and intermediate itsends the tube is fitted with a handle 7.

On that end of the tube which carries the pump is mounted a cap 8 havingon one side an annular flange 9 which ts snugly within the tube 5, andserves to hold the cap thereon. The cap also carries a nipple 10, whichprojects from both sides thereof. That end of the nipple which projectsfrom the outside of the cap is interiorly threaded as indicated at 11,into which is screwed the barrel 12 of the pump. The pump plunger 13 isprovided with a handle 14.

That portion of the pump barrel which screws into the nipple 10terminates in a Specification of Letters Patent.

Application filed June 28, 1909.

Patented May 10, 1910. .arial No, 504,757.

tapered portion 15 the end of which is cut ofi' on a slant to form theseat 1G of a check valve 17 which is pivoted at 18 to said end of thebarrel so as to open downwardly.'

The back of the valve is engaged by a spring 19 secured to the pumpbarrel, and serving to normally hold the valve seated.

By the herein described arrangement of parts the pump is separablyconnected to the nipple 10, the discharge end of the pump readilyentering the same, by reason of its taper. W hen the device is not inuse, the pump can be unscrewed and removed. This is desirable as itpermits repairs to the pump and valve to be readily made.

The pump herein described is an .air pump, Athe air being dischargedfrom the valved end of the barrel 12, the valve 17 operating as a checkvalve in the ordinary manner.

That portion of the nipple 10 which eX- tends from the inner side of thecap 8, is located within the tube 5 when the cap is in place thereon,and this portion of the nipple is surrounded by a conical sleeve 20,extending from the cap to the end of the nipple. This sleeve serves tobrace the nipple, and also acts as a shield to prevent excessive heatingof the adjacent end of the tube, as well as the valve. In the tube 5, atthe junction of the tapered portion 6 and the main portion, is mounted atransverse partition 21 having perforations 22. This plate serves as agrate, and prevents the coutents of the tube from being blown into thehole, and thus clogging up the same.

In use, the cap S is removed and the tube 5 is filled with hay, or someother combustible material, together with sulfur, or some otherfumigating substance. The contents of the tube are then lighted, and theCap 8 is replaced. The tapered end of the tube is now inserted into themouth. of the gopher' hole, and the smoke and fumes from the smoulderinghay and sulfur are blown thereinto, upon operating the pump. The taperedend of the tube enables it to be tightly wedged into the hole, so thatno smoke and fumes can escape except into the hole.

le claim:

A gopher exterminator comprising a tube, a cap on one end thereof, anipple on the cap projecting from both sides thereof, a pump Intestimony whereof We ax our signaconneoted to that portion of the nippletures in presence of two Witnesses.

which is on the outside of the Cap, and a, EDWARD C. DUCKETT. conicalsleeve surrounding that portion of FRANK B. LLOYD.
